The radio remote controls adopted by Greifenberg are the result of years of field experience in terms of operating range and ease of use. They are comfortably usable with safety gloves and feature an extremely robust “case” capable of withstanding drops and violent impacts. With a convenient shoulder strap, they can be held with one hand, and thanks to buttons marked with specific icons, the maneuvers during operation are incredibly simple. A powerful battery ensures a full workday’s operation, and the standard supply also includes a spare battery and a charger.

The brain of the radio system is located in the key inserted into the remote control, where communication codes and protocols are stored.

From the remote control, it is possible to perform all the maneuvers typically executed from the machine's touch screen. In fact, you can turn the diesel engine on and off, increase and decrease the speed of the ropes, set and update the end-of-line or load point, make movements outside the set parameters using the dedicated “bypass” button, start the automatic working cycle to let the machine operate autonomously, control traditional carriages by opening and closing the blocks on the ropes, and perform all maneuvers on the motorized carriages, controlling both the motor and the lifting and lowering speed.

Through the remote control, it is also possible to set the maximum lifting point of the carriage to prevent the hook from being raised too much, as well as the maximum unwinding of the rope, avoiding unrolling the entire rope wound on the carriage drum. If the rope is shortened, it is possible to reset the maximum lifting point, updating it to the new rope length.

The same remote control can also integrate the management of Fortronics electronic chokers with an anti-accidental opening system.

The Radio System includes a perfectly coded and integrated radio frequency repeater. The remote controls can operate with one or more repeaters, making the working distance virtually infinite, even allowing it to overcome bumps, buildings, and obstacles of any kind, thereby extending the operational distances. The repeater is housed in a small, durable casing, and inside, a powerful rechargeable battery ensures operation even during an intense workday. The repeater should be placed on the peaks of bumps or beside structures so that it has a strong connection both to the transmitter and the receiver. Activation is straightforward, performed with a single button, and the distance is reset with one click.

Greifenberg understands the external working conditions with temperatures ranging from below freezing to scorching heat, snow, water, and humidity. The Radio System is resistant to the elements: with an IP65 rating, selected components, and contacts treated with anti-corrosive materials, these are the guarantees of a product designed for tough working conditions. Maximum reliability ensures precise, punctual, and indisputable controls. Transmitters, repeaters, and receivers are ready for non-stop work.

The traction rope ejector is able to maintain the tension of the rope on the drum in such a way that it prevents any slack that could compromise the correct winding and the rope's durability. This means that the traction rope is redirected onto a motorised pulley, which ensures that there is always the correct tension between the roller and the pulley, safeguarding the integrity of the steel cable. The traction rope continuously travels thousands of kilometres between the "wind" and "unwind" functions. For this reason, the pulley is made from special steels and thermally treated, while the hydraulic motor applied is suitable for intensive work.

The traction force on the rope is adjustable to ensure sufficient extraction force while reducing fuel consumption. A traditional extraction pulley on a cableway can consume up to 10/15 horsepower, impacting fuel consumption by as much as 8% of the machine's daily fuel usage. Adjusting the counterforce and hydraulic pressure settings allows these values to be halved, reducing fuel consumption and harmful emissions.

In cases where the work is carried out on steep slopes and medium-length tracks, it is possible, via a control on the panel, to deactivate the traction ejector system and use the pulley as a simple freewheel pulley with minimal friction.

This system can work at speeds of up to 10 metres per second for the traction rope. Therefore, even in the case of very long and flat stretches where the catenary of the traction rope becomes very pronounced, there is no problem with the roller, even at high speeds, ensuring maximum preload on the traction rope.

ATG, Automatic Travel Greifenberg, is the electronic control and management system, a true artificial intelligence, meaning the machine’s ability to travel along the rope fully autonomously and in automatic cycle. The ATG system takes into account various critical points, such as the supports, potential entanglements of the load, excessive power demand on uphill sections, overspeed during descents, deceleration and acceleration speeds, and, if necessary, updating the loading point. It continuously coordinates the work with responsiveness, precision, and accuracy.

To activate the ATG, the machine must recognise the two extreme points of the line, which are stored as “start of line” and “end of line” through an intuitive procedure on the control panel. Subsequently, it will be possible to store the points along the line where the supports are located, which will be interpreted as sensitive points. To ensure smooth translation, the electronic system allows you to set the distance from the support at which we want to slow down and the distance at which, after passing it, we want to accelerate again and return to the normal speed. The distances and the amount of deceleration can be entered differently depending on which part of the journey we are undertaking and, consequently, how we approach the supports.

For example, when carrying heavy loads downhill, it is necessary to slow down gradually from a proper distance, and once the support is passed, speed is quickly resumed to avoid rope and load oscillations. On the other hand, if the transport is going uphill, it is sufficient to slow down close to the support, as the weight and gravity already assist with deceleration.

Everything is under control during the journey; the machine, thanks to its pressure transducers and position encoders, constantly monitors the effort and, if it detects any abnormal spikes (caused by jams or resistance), it deactivates the automatic system, halting the journey while still allowing for manual operation. The ATG function also allows for the updating of the loading or unloading point via the radio control. When the transport needs to frequently change its destination to pick up or deposit material in different locations, simply activate the "store new end point" function from the remote control, and the machine will stop exactly at the specified location.

The colour display for machine data and line data offers greater accessibility, enhanced intuitiveness at first glance, ease of line parameterisation, and a simplified procedure for synchronising the remote controls of the trolleys. The new series of displays allows for quick checks, constantly informing the operator about position, efforts, shoe positions, engine revolutions, fuel consumption, and fuel levels. The most relevant data are displayed both in analogue and digital formats to increase the immediacy of reading.

The cableways, in the electronic safety management system, have the function of forced and preset loosening of the supporting cable. This function allows the operator, by pressing a button called "support lowering", to activate an autonomous system that converts hydraulic flows, accelerates the engine, and moderately activates the hydraulic pumps. Any possibility of the trolley colliding with the end of the line is prevented by this mode. The supporting cable lowers until it brings the load in contact with the ground, stopping any uncontrolled movement. Once the operator has pressed the button to activate the function, they can move away and position themselves in safety. Your machine will autonomously carry out the manoeuvre.

Total control, verification, and statistics.

Every alarm, abnormal use, and operation outside the parameters are automatically recorded and stored in a dedicated memory. Data such as engine over-revving, over-pressures, over-speed, oil and water temperature alarms, etc., are immediately logged. It will be easy for the owner to check how the machine is being used, both by their employees and in the case of rentals to third parties. Even for service interventions, everything becomes quicker, reducing management costs. Information is available to assist with the machine's durability and maintenance.

Our technicians with you, whenever you want, on your site to help you solve problems.

Through remote assistance, simply activate a GPRS connection and allow the connection to your equipment. This always happens exclusively with the operator's authorisation for the machine. Once connected, our electronic and hydraulic technicians can work on the machine as if they were there on site. Maximum speed of intervention and reduction of costs and waiting times. The innovation of safety always by your side.

The remote controls adopted by Greifenberg are the result of years of field experience regarding operational capacity and ergonomics of use.

The brain of the radio system is located in the key inserted into the remote control, where codes and communication protocols are stored.

From the remote control, it is possible to perform all the manoeuvres normally carried out via the machine’s touch screen panel. Indeed, you can switch the diesel engine on and off, increase or decrease the speed of the ropes, set and update the end of line or loading point, make movements outside the set parameters via the dedicated “by-pass” button, start the automatic working cycle for autonomous operation, control traditional trolleys by opening and closing the blocks on the ropes, and even carry out all manoeuvres on motorised trolleys, controlling both the motor and the lifting and lowering speed. Through the remote control, it is possible to set the maximum lifting point of the trolley to ensure the hook is not accidentally lifted too high, as well as the maximum unwinding of the rope to prevent unspooling the entire rope wound on the trolley drum. If the rope is shortened, it is possible to reset the maximum lifting point to reflect the new length of the rope.

The same remote control can also integrate the management of Fortronics electronic chokers with an anti-accidental opening system.

The Radio System includes a perfectly coded and integrated frequency repeater. The remote controls can operate with one or more repeaters, extending the working distance infinitely and overcoming hills, buildings, and obstacles of all kinds, thus expanding operational range. The repeater is housed in a robust, compact enclosure, and inside it, a powerful rechargeable battery allows operation throughout a demanding working day. The repeater should be placed at the top of hills or beside structures to ensure a good connection both to the transmitter and the receiver. Activation is very simple, done with a single button press, and the distance is reset with one click.

Greifenberg understands the challenging external working conditions, with temperatures ranging from sub-zero to scorching sun, snow, rain, and humidity. The Radio System is immune to the elements: rated IP65, with selected components and contacts treated with anti-oxidant materials. These are the guarantees of a product designed for heavy-duty work. Maximum reliability ensures precise, punctual, and indisputable commands. Transmitters, repeaters, and receivers are ready for non-stop work.

The expeller of the pulling rope is designed to maintain tension on the drum in such a way that no slack is created, which could compromise the correct winding and the durability of the rope itself. This means that the pulling rope is redirected onto a motorised pulley, which ensures that the correct tension is always maintained between the roller and the pulley, protecting the integrity of the steel cable. The pulling rope continuously travels thousands of kilometres between the “wind” and “unwind” functions, so the pulley is made from special steels and is thermally treated, while the hydraulic motor applied is suitable for intensive work.

The traction force on the rope is adjustable to ensure sufficient pulling power while reducing fuel consumption. A traditional extraction pulley on a cableway can absorb up to 10-15 horsepower, affecting fuel consumption by up to 8% of the machine's daily fuel use. Adjusting the counter-force and hydraulic pressure allows these values to be halved, reducing fuel consumption and harmful emissions. In cases where the work takes place on steep slopes and medium-length tracks, it is possible, via a command on the control panel, to disengage the pulling expeller system and use the pulley as a simple idler pulley without excessive friction.

This system can operate at speeds of up to 10 metres per second for the pulling rope, so even in very long and flat stretches where the catenary of the pulling rope becomes very accentuated, there are no issues with the roller, even at high speeds, ensuring maximum pre-tension on the pulling rope.

ATG, Automatic Travel Greifenberg, is the electronic control and management system, a true form of artificial intelligence, meaning the machine's ability to travel along the rope autonomously and in automatic cycle. The ATG system takes into account various critical points, such as the supports, potential entanglements of the load, excessive power demand when climbing, over-revving during descents, deceleration and acceleration speeds, and updates the loading point if necessary. It continuously coordinates the work with responsiveness, precision, and accuracy.

To activate the ATG, it is necessary to register the two extreme points of the line, which are stored as "start of line" and "end of line" through an intuitive procedure on the control panel. Subsequently, it will be possible to store the points along the line where the supports are located, which will be interpreted as sensitive points. To achieve a smooth translation, the electronic system allows you to set the distance at which you want to decelerate before the support and the distance at which, after passing the support, you want to accelerate and return to normal speed. The distances and the amount of deceleration can be set differently depending on the direction of travel and, consequently, the entry onto the supports. When transporting heavy loads downhill, it is necessary to gradually decelerate at an adequate distance, while after passing the support, the speed is quickly regained to avoid rope and load oscillations. Conversely, if the transport is taking place uphill, it is sufficient to slow down close to the support, as the weight and gravity already contribute to the deceleration.

Everything is under control during the journey, as the machine, thanks to its pressure transducers and position encoders, constantly monitors the effort. If it registers any abnormal peaks (caused by blockages or resistance), it deactivates the automatic system, stopping the journey, but always keeping the manual mode available. The ATG function also allows you to update, via the radio control, the loading or unloading point. When the transport frequently changes the arrival point to pick up or deposit materials in different locations, simply activate the "store new end point" function directly from the radio control, and the machine will stop its journey exactly at the determined location.
